2. Relevant equations

3. The attempt at a solution

Really I have no clue where to start on this guy. We did a problem sort of similar to this in class but we were given acceleration so we could use the form of

Vp = at [tex]\hat{u}[/tex]

From there we could say that Vp = [tex]\dot{r}[/tex] [tex]\hat{u}[/tex]_{r}+ r[tex]\dot{\theta}[/tex][tex]\hat{u}[/tex]_{[tex]\theta[/tex]}= at [tex]\hat{u}[/tex]

I don't see how I could apply this equation in this problem, or really even if it does apply.

Any hints would be greatly appreciated, just to get a start in the right direction!
